Relying on the Judo Friendship "Ji-Ta-Kyo-Ei" principle, Ko Dojo often takes benefit of hosting from friend clubs and - similarly - offers other clubs the same opportunity.

Athletes willing to spend the night in Milano on the tatami within their sleeping bags in a warm and friendly environment are entitled to signal this esigency; correspondingly, judo friends transiting through Milan ( even for Expo 2016 ) are allowed to take benefit of this opportunity.

Spending the night in the sleeping bags will be free of charge for athletes and sensei's from friend clubs, while the other ones will be asked for a cheap token price.
